KST A20-3813 20 mm digital brushless HV servo up to 430 Ncm
Item number: KST-1024
EAN: 4260461681316
KST presents with the A-series high-end servos, which was developed especially for the hard everyday and competition use in wing models.
For this servo special gears with phosphor bronze gears with a hardness between 40 and 50° and axles made of stainless steel are used. This combination ensures maximum longevity and reliability, even when the gear grease deteriorates in their function after long use. The Phosphor Bronze gearbox still offers excellent friction losses, ensuring longer life and trouble-free operation.
Furthermore, the A-Series uses new electronics to reduce "BACK EMF" (interference with other electronic components in the model).
All servos are subjected to a 2000 Hz vibration test. This test ensures that the servos will still function under the most adverse conditions, such as those encountered with internal combustion engines. An anti-jam circuit prevents the motor and electronics from burning out if, for example, a linkage or rudder jams.
